Strategic Objectives
• Decode the atomistic mechanisms of sluggish diffusion in high-entropy alloys.
• Identify the tipping points of phase transformation stasis.
• Master the calculation of tracer diffusion coefficients in concentrated solutions.
• Predict material longevity in extreme, chemically complex environments.
The Core Challenge
Traditional thermodynamic models fail to explain why atoms stall in complex alloys, leading to unpredictable material failure or phase instability.
